A Sent one comes to a mortal, names a thing that must be done in the Warden's name, and leaves the doing to them; blessing follows the deed, or does not follow the refusal. Most people go their whole lives without meeting one, and a fair number of those who claim to have met one were lying or drunk or worse. That they are rare is either the mark of a careful god or a thin one.",
